Recently in the study of Hadoop, first through the online a lot of tutorials to build a fully distributed environment, in the distributed environment to run WordCount is also successful, then intend to write their own Mr to deal with the actual business, before the real development began to build a good development environment ah, So I think of Eclipse, but then we have a lot of problems:1, the first is to

When you connect the hadoop1.2.1 cluster through eclipse in a Win7 environment, you will experience the following error: Exception in thread ' main ' java.io.IOException:Failed to set permissions of path: \tmp\hadoop-administrator\mapred\stagi Ng\administrator-519341271\.staging to 0700 At this point only need to modify the Org.apache.hadoop.fs.FileUtil file and recompile, the simple solution is as follows

1. Create a new Java project2, the Hadoop source code extracted, and then to the SRC directory, src under the core, HDFs, mapred folder copied out3. Paste the copied three folders into Java Project SRC4, the SRC removed, right-click Properties to find5. Add a Resource folder6. Join the dependent JAR package. Go to7. Find the disk where the Hadoop source is located, and import all the jar packages under Lib

Eclipse remote debugging of hadoop codeZxxJPDA introduction Sun Microsystem's Java Platform Debugger Architecture (JPDA) technology is a multi-layer Architecture that allows you to easily debug Java applications in various environments. JPDA consists of two interfaces (JVM Tool Interface and JDI), one Protocol (Java Debug Wire Protocol), and two software components (backend and front-end) used to merge them

It is common to prefer to set the environment variable in the script that launches the program, so that the script can run its own environment with the appropriate environment variable values.

This problem arises, I first went to look for a few questions:1. Whether the file is Utf-82. Upload to Hadoop in Linux and see if it's garbled on Linux3. There is no problem, go to check Eclipse, Project engineering to change to Utf-8, found no4. After a look at the introduction, the eclipse's system settings were changed to Uft-8, you canUTF-8 settings in Eclipse1.windows->preferences Open the Preferences
